权限被拒绝访问与瓶

Question

每当我试图打开posts文件夹Python3.6到文件夹，我得到一个错误：

Traceback (most recent call last): 
    File "C:\Python36-32\lib\site-packages\flask\app.py", line 1997, in __call__ 
    return self.wsgi_app(environ, start_response)

    with open(str(find_recent_post_name())) as post: 
PermissionError: [Errno 13] Permission denied: 'posts/' 

我main.py文件：

from flask import Flask 
from flask import render_template 

app = Flask(__name__) 

def find_recent_post_name(): 
    import glob 
    posts = glob.glob("posts/") 
    return posts[len(posts) - 1] 

def find_recent_post(): 
    with open(str(find_recent_post_name())) as post: 
     newest_post = post.readlines() 
    return newest_post 


@app.route("/") 
def index(): 
    return render_template("index.html", newest_post=find_recent_post()) 

if __name__ == '__main__': 
    app.run(debug=True) 

我Python版本是v3.6.1和Flask v1.12.0

编辑：调试代码和使用PowerShell似乎工作。

烧瓶不是问题。您可以更改文件夹/posts/上的权限，也可以将烧瓶作为拥有read访问权限的用户运行。

$ chmod 755 <folder names> 

授予访问权限谁跑的烧瓶应用的用户，或者你可以使用：

$ sudo python main.py 

为admin运行或运行烧瓶谁已经拥有访问权限的用户。并注意您应该在部署时添加相同的设置。因此uwsgi或gunicron的工作人员或者在部署上运行应用程序应该使用相同的凭据运行。

请注意，您应该user兼得read或4访问读取文件内容的，并有execute或1访问能够cd进去。
